压缩机叶轮用FV520B-S材料的热处理工艺
摘要：
本发明公开了一种压缩机叶轮用FV520B-S材料的热处理工艺，属于热处理工艺技术领域，该工艺包括以下步骤：(1)固溶化处理，在1050℃下保温2.0～3.0小时，然后风冷；(2)调整处理，在850℃下保温2.5～3.5小时，然后风冷；(3)室温停留，调整处理后的FV520B-S材料在室温下停留8小时；(4)一次时效处理，在605-615℃保温4～5小时，然后风冷；(5)经步骤(4)一次时效处理后的FV520B-S材料，增加二次时效处理，即在605-615℃保温4～5小时，然后风冷。经本发明处理后的压缩机零件，其综合机械性能的一次合格率再次获得提高。
摘要（英）：

The present invention discloses a compressor impeller FV520B-S material heat treatment process, and belongs to the technical field of heat treatment process, the compressor impeller FV520B-S material heat treatment process comprises the following steps: (1) solid solution treatment, to be more specific, thermally insulating at 1050 DEG C for 2.0-3.0h, and then cooling in air; (2) adjustment treatment, to be more specific, thermally insulating at 850 DEG C for 2.5-3.5 hours, and then cooling in air; (3) room temperature staying, to be more specific, staying a FV520B-S material after the adjustment treatment at room temperature for 8 hours; (4) first aging treatment, to be more specific, thermally insulating at 605-615 DEG C for 4 to 5 hours, and then cooling in air; and (5) additional secondary aging treatment of the FV520B-S material after the first aging treatment, to be more specific, thermally insulating at 605-615 DEG C for 4 to 5 hours, and then cooling in air; and the first-passyield of the general mechanical performance of a compressor part processed by the compressor impeller FV520B-S material heat treatment process can be improved again.
